Pipe



Patented Mar. 18, 1941 UNITE@ STATES PATENT @FFME 4 Claims.

My invention relates to improvements in smoking pipes.

The primary object of the present invention is to provide an improved, economical and greatly 3 simplified bafle adapted to be tted to the bit or mouth-piece of a pipe and engage a chamber witliin the stern to divide said chamber into separate compartments and also to form a tortuous passage therethrough, `to delay the passage V) of smoke from the bowl to cool and dry the same.

Another object of the invention is to provide a new and greatly simpliiied structure of the character described, that is also adapted to di- E vide a chamber in the smoke passage into sev- T) eral compartments for trapping moisture.

A further object is to provide an improved and simplified construction of the type set forth, that will automatically remove undesirable accumulations from a chamber in the smoke-passage, by

2o the simple expedient of rotating and withdrawing the bit from the bowl.

A still further object of my improved and sirnplified baiile, is to provide a tortuous passage for cooling and drying smoke passing therethrough,

25 that may be easily and thoroughly cleaned.

The invention consists in the particular construction and arrangement of parts as disclosed in the drawing forming a part of the present application, and in which- Si) Fig. l is a broken plan view of a pipe, partly in horizontal longitudinal section, disclosing my improved device applied thereto;

Fig. 2 is a broken side elevation, disclosing a portion of the pipe in vertical section;

Se Fig. 3 is an enlarged, broken horizontal sectional View of the stem only of a pipe, with the improved device in section to more clearly disclose the construction thereof;

Fig. l is an enlarged, transverse sectional view it) taken on line i--i of Fig. 2 in the direction incated;

Fig. 5 is an enlarged elevation of one of the baliles as seen transversely; and

Fig. 6 is an enlarged detailed view of the par- 45 ttion.

Referring to the drawing:`

1he numeral I is used to designate the bowl of a pipe having the usual stem 2 with its usual bore counterbored or enlarged to provide a chamber 50 3s. A bit or mouth-piece t has the usual reduced portion 6 for engaging the bore of the stem 2 in the usual manner. A flat, longitudinally disposed plate or partition I' is provided with a reduced end 'I' for preferably detachably engaging the usual bore of the mouth-piece or bit fl. This partition or plate l extends substantially the length of the chamber 3, when the bit 4 is attached, and is provided with several apertures 8 and inclined slots 9 in one edge thereof to receive and hold inclined elliptical baies II, each 5 baffle II being provided with a slot l2 for straddling the plate 'I and intersecting an aperture 8 therein to provide a tortuous passage to delay and thereby cool smoke passing therethrough.

N'hile these bafes I I are elliptical in shape the 10 edges thereof, by reason of their inclined relation to the plate l, lie within the confines of a cylinder, as defined by the inner walls of the chamber 3, and contact said walls to form separate compartments within said chamber. 15

As the battles II straddle the plate or partition l, it is obvious that separate compartments will be formed on opposite sides of said plate 1, and, as the slots I2 of said baiiies I I intersect the apertures 3 of said plate, that there will be a tortuous 20 passage formed by said plate 'I and baies, said passage communicating with and connecting not only opposite sides of said plate 'I and compartments thereby formed, but also forming a tortuous passage through the slots l2 and apertures 25 t from the bowl I to the mouth-piece 4.

Accumulations within the chamber 3 and several compartments thereof may easily be removed by the simple expedient of rotating the mouthpiece 4 and plate l which will cause the edges of 30 the baiiles II to dislodge or scrape the walls of the chamber. Withdrawal of the plate 'I and balfles II attached thereto will remove said accumulations from said chamber.

Owing to the open construction of the plate 'l 35 and lateral wings or baffles extending therefrom, said plate and baffles may be easily and thoroughly cleaned before returning to operative position. Thus a clean pipe may be constantly had.

By means of this improved and greatly simplii0V fied construction a dry, cool smoke is provided.

I am aware that the present state of the art discloses attachments for pipes for retarding the passage of smoke therethrough for cooling the same and preventing, to a certain degree, precipi- 45 tation or condensing of moisture. I therefore do not wish to claim such a combination broadly.

Having described my invention, I claim- 1. A baiiie for a pipe having a bowl and a chamber in the stem thereof, comprising a longitudinally disposed partition within said chamber and provided with apertures; and slotted baffles mounted on said partition and having the slots intersecting the apertures of said partition to provide a tortuous passage through said chamber. 55

2. A baffle for a pipe having a bowl and a chamber in the stem thereof, comprising a longitudinally disposed apertured plate within said chamber and dividing the same lengthwise into compartments; and slotted baffles mounted on said plate with the slots of said bafes intersecting the apertures of said plate and further dividing said chamber into compartments connected through said intersecting apertures and slots.

3. A baiiie for a pipe having a bowl and a chamber in the stem thereof, comprising a longitudinally disposed apertured plate within said chamber and provided with inclined slots; and slotted baflles mounted within said inclined slots with the slots of the bailles intersecting the apertures of said plate, said plate and baffles separating said chamber into compartments and said apertures and intersecting slots connecting said compartments to form a tortuous passage.

4. A baie for a pipe having a bowl and a chamber within the stem thereof, comprising a longitudinally disposed apertured plate mounted Within said chamber and dividing the same into opposite chambers, said plate being further provided within inclined slots in one edge thereof; and slotted baiiles mounted within said inclined slots on said plate, the slots of said baffles intersecting the apertures of the plate and said baffles further dividing said opposite chambers into compartments connected by said intersecting slots and apertures, to provide a tortuous passage and traps through said chambers.
